ROBERT TURNER, OF DES MOINES, IOVA, ASSIGNOR TO THE DUPLEX TYPEIVRITERCOMPANY, OF SAME PLACE.

TYPE-WRITING MACHINE.

SPECFICATION forming part of Letters Patent No. 675,989, dated June 11.,1901. Application filed June 7. 1899. Renewed March 16, 1901. Serial No.51,554. (No model.)

To LU whom it 11mg/ concern.'

Be it known that I, ROBERT TURNER, of Des Moines, in the county of Polk,in the State of Iowa, have invented new and useful Improvements inType-VVriting Machines, of which the following, taken in connection withthe accompanying drawings, is a full, clear, and eXact description.

My invention relates to type-Writing machines.

My object is to improve their construction byprovidinga novel marginalstop and a novel key-lever or action lock, the margin stop or regulatorbeing manually adjustable and being also connected to a key-lever,whereby it can be depressed out of the path of the carriage operated atthe keyboard, the key-lever lock being operated by the movement of thefront rail of the traversing carriage to lock the universal bar, wherebyit and the escapement are locked and the key-levers renderedinoperative.

It is constructed and operated as follows, reference being had to theaccompanying drawings, in Which- Figure 1 is a front elevation of atype-writing machine, part of the carriage being broken away. Fig. 2 isa rear elevation of the front' of the carriage and track and part of therear of the body of the machine, the dotted circle indicating thealarm-bell. Fig. 3 is a sectional elevation detailing part of themarginstop mechanism. Fig. 4 is an elevation detailing that part of thekey-lever-locking mechanism which is not shown in Fig. 1. Fig. 5 is anelevation detailing that part of the bell-ringing mechanism which is notshown in Fig. 2.

A is a suitable frame having a keyboard 2 and top plate 3, and 4 is thefront trackway for the traversing carriage, of which 5 is the frontrail. This rail is in the form of a channel-iron and is provided withslots 6 7, and its front face is provided with a scale, as shown. In theconcaved or channeled back slides 8 i) are mounted, each havinga handle10 pivoted therein and projecting forward through a slot 6 or 7 beyondthe front of said rail. A plate 11 in front of said rail is secured toeach slide and provided with a pointer 12. Racks 13 are secured in thechannel of sail rail, and 14 is a pawl secured on each slide-handleengaging with one of said racks. These slides are thus separatelyadjustable to determine the margin on either side of the sheet and tovariably determine the length of a line ot' print, said pawls holdingthem against outward movement. Upon or in the front track a sliding bar15 is suitably mounted, having a lug or arm 16 projecting above thetrack into position to be engaged by a dog 17 on the slide 9, said barbeing adapted to yield with such engagement and rock the bell-crank 18,lift the rod 19 and lever 20, and tilt the bell-crank 22 to bring itsarm 21 under the universal bar 23 and lock it against depression by anykey-lever 24, thus locking the escapement to which the rod 25 issuitably connected, said escapement not being shown nor described, as itdoes not constitute any part of my invention. A spring 26, connected tosaid bell-crank, retracts all of the members of this mechanism wheneversaid slide or dog is disengaged. This mechanism locks the printingmechanism at the predetermined point indicated by the pointer on theright in Fig. 1. The slide 8 is also provided with a dog 27, normallycarried by a pin, as shown in Fig. 2, which when the carriage isretracted engages with the lug 16 and stops the carriage to begin a lineof print at the point indicated by the pointer on the left in Fig. 1 toregulate the width of the margin on the left side of the paper.

To permit printing in the left-hand margin, a finger-key 29 raises a rod30 and rocks a lever 3l, connected to the slide 15, whereby the lug orstop 16 is depressed out of the path of dog 17, and thus permits thecarriage to be moved to the point desired. This also removes the stop 16from the path of the dog 17 and permits printing in the right-handmargin.

In Figs. 2 and 5 a bell-ringing device is shown, comprising a slide 32,mounted on the track 4 bya pin and angular slot 34 and having a lug 33normally projecting above said track into the path of the dog 17, acrank 35, connected to said slide, a spindle 36, carrying said crank,ahammer 37 on said spindle, and a spring 38, whereby the pawl 17 willforce said stop and slide to the left until it is IOO depressed by saidangular slot out of said path, whereupon said spring will retract saidparts and at the same time cause the hammer to strike a blow upon thebell 39.

Vthat I claim as myvinventien, and desire to secure by Letters Patent,is

1. In a type-writing machine, the combination with a traversingcarriage, the front rail of which is provided with a scale, and withhorizontal lengthwise slots adjacent to its ends, of slides upon therear of said rail, a horizontal pin on each slide projecting forwardthrough a slot, and a pointer on each pin in front of said scale wherebyeither slide can be separately adjusted and its pointer set to regulatethe right or left margin.

2. In a type-writing machine the combination with a traversing carriagehaving a longitudinally-slotted front rail, provided with a scale on itsouter face, of separate slides upon the back of said rail, separatepointers in front of the rail connected through said slots to saidslides and separate handles connected to said slides whereby they can beseparately adjusted to determine the margin either upon the right or theleft side of a sheet.

3. In a type-writing machine the combination with a traversing carriagehaving a slotted front rail, and a scale on the outer face of said rail,of separate racks upon the back of and adjacent to the ends ot' saidrail, separate slides having pawls engaging with said racks, separatepointers in front of said rail and connected through said slots, to saidslides and a handle on each slide whereby it is adjusted and its pawlshifted, to determine the margin upon either the right or leftside of asheet.

4. In a type-writing machine the combination with a traversing carriagehaving a front rail provided with a scale and a longitudinal horizontalslot, a slide upon said rail, a pointer connected to said slide throughsaid slot, and a dog upon said slide, of a margin-stop below the railand projecting upward normally in the path of said dog, and means todepress the stop from said path to permit the dog to pass over it whenthe carriage is shifted from left to right.

5. In a type-writing machine the combination with a traversing carriage,having a scale and longitudinal slots in its front rail, slides uponsaid rail, pointers connected to said slides through said slots andseparately adjustable, and a dog on each slide, of a margin-stop betweensaid dogs and normally in their path, a lever connected to said stop, akey-lever, and a rod connecting said levers, whereby said stop is swungout of said path by operating said lever.

In witness whereof I have hereunto set my hand this 8th day of May,189i).
